Question

Find the volume of the cylinder if height (h) and radius of the base (r) are as given below.
(1) r = 10.5 cm, h =8 cm
(2) r = 2.5 m, h = 7 m
(3) r = 4.2 cm, h = 5 cm
(4) r = 5.6 cm, h = 5 cm

Solution

Volume of the cylinder = π r²h
(1) r = 10.5 cm, h =8 cm
Volume = π r²h = `22/7 xx 10.5 xx 8` = 2772 cubic cm

(2) r = 2.5 m, h = 7 m
Volume = π r²h = `22/7 xx 2.5 xx 2.5 xx 7` = 137.5 cubic cm 

(3) r = 4.2 cm, h = 5 cm
Volume = π r²h = `22/7 xx 4.2 xx 4.2 xx 5` = 277.2 cubic cm 

4) r = 5.6 cm, h = 5 cm
Volume = π r²h = `22/7 xx 5.6 xx 5.6 xx 5` = 492.8 cubic cm 

  Is there an error in this question or solution?
